Feed mechanism of the present invention is fixed on the middle part of frame 1, and it comprises feeding hydraulic cylinder 23, the slide plate 22 of fixedlying connected with the piston rod of feeding hydraulic cylinder 23 and is fixedly mounted on feeding table 2 on the slide plate 22.Adopting above-mentioned hydraulic pressure feed mechanism is in order to realize self-feeding, as operating automatically, also can adopt common feed mechanism to replace or artificial feeding.
In grinding when work,, the friction between two emery wheels and the workpiece can produce a large amount of sparks, in order to prevent that sparks flying off in all directions, thereby guarantees that the staff is not injured by it, is provided with protective cover 17 above described two emery wheels, is provided with protective plate between two emery wheels and feed mechanism.The base of protective plate is fixed on the frame; A side of protective cover 17 is hinged and connected on the shielding support, and the top margin of another side and protective plate is provided with the locking device that cooperatively interacts; The shielding support bottom is fixed on the frame.Because the friction between two emery wheels and the workpiece also can make the temperature of emery wheel and workpiece sharply raise simultaneously, the too high meeting of temperature makes emery wheel and workpiece deformation, have a strong impact on the quality of production, therefore, be fixed with water spout 19 at the top of protective cover 17, when work, carry cold water, cooling in time for emery wheel and workpiece in the work by water spout 19.
Among the present invention, be connected to distribution box, pedal type switch 2 is installed on frame 1 as the motor of engine; Displacement hydraulic cylinder and feeding hydraulic cylinder all are connected to hydraulic control device.
Before starting working, the initialization gap of two emery wheels 20 to be set at first.Unclamp nut 24,, drive travelling gear 10, thereby rotary screw 26 promotes contiguous block 31 and moves, and drives whole revolving power mechanism by main spindle box 16 when contiguous block 31 moves and moves, and determines the initial bit of emery wheel 20 earlier by rotary handle 4.Its transmission process is as follows: rotary handle 4, drive drive link 5, and by drive bevel gear 6, driven wheel of differential 9 drive splines axles 8, splined shaft 8 drives screw rod 26 by travelling gear 10; Because nut 24 is fixing, the rotation of screw rod 26 makes it produce axial displacement, thereby drives main spindle box axial displacement by contiguous block 31, and then makes emery wheel 20 reach the assigned work initial bit.Fastening nut 24 more at last is with its fixed-site.
During work, at first open revolving power mechanism, the staff is placed on workpiece on the feeding table 21, start the feeding hydraulic means, realize self-feeding, the front end of workpiece puts in and is squeezed in the slit between two emery wheels 20, carries out grinding, controls displacement hydraulic cylinder 11 simultaneously, piston 27 is moved lentamente laterally, because in turning handle not, screw rod does not rotate yet, so, when piston 27 moves laterally, drive emery wheel 20 and move laterally, the gap between two emery wheels 20 is strengthened gradually, finally finishes the grinding to workpiece two inclined-planes.
Thus, the present invention can realize workpiece is carried out the purpose that two planes of symmetry are processed simultaneously, its technological process is short, difficulty is low, particularly can be little to two-sided machining accuracy height, production efficiency height, the production loss of the little workpiece of appearance and size, simultaneously, easy to operate, reduced working strength of workers, can guarantee that also the workman can have a working environment preferably.
